Hi David, We use secure IMAP4 server publishing quite a bit and it works nicely! Thanks!

I was just going to say to check your Exchange server. You do have the option in IMAPI4 service to change from Basic Authentication to NTLM. Right-mouse click Default IMAP4, click Properties, then click Access tab, and click Authentication... button. If basic authentication is fine, start thinking about using SSL for it. On the ISA server do you have under Site and Content Rules - SMTP Outbound rule? It should have been created by your Mail Secure Wizard to allow your exchange to send outbound messages. Also, verify that your Exchange can resolve external FQDN, (example - nslookup www.isaserver.org <http://www.isaserver.org/> ) -----Original Message----- From: Simon Weaver [mailto:Simon.Weaver@xxxxxxxx] Sent: Friday, June 20, 2003 6:35 PM To: [ISAserver.org Discussion List] Subject: [isalist] RE: enable IMAP from Web
